Kenwood TS-120S Operating Manual page 8

@ VOX (VOICE OPERATED TRANSMIT) SWITCH
This function is used for SSB VOX or CW semi-break-in -
peration. In the MAN (manual) position, the transceiver is
keyed by either the standby switch or the microphone PTT
switch for VOX operation, the standy switch remains in
RED. (See page 12.)
METER SWITCH
During transmission, the meter switch determines meter
function. The switch selects between:
REC Kae vdedsansearee The meter monitors the output of the final
stage power amplifier during transmis-
sion. During SSB operation, adjust the
MIC control so that the meter pointer is
within the ALC zone. Similarly, adjust the
CAR control for CW operation.
IC (TS-120S).... The meter monitors final stage collector
current.
RF (TS-120V)... In this position the meter monitors the
relative RF output of the transceiver.
@ FIX (fixed channel) SWITCH
The TS-120S(V) has a built-in fixed channel oscillator
(crystals are user-provided, optional) which is activated by
the FIX switch for fixed channel or VFO operation.
(® SUBDIAL
The subdial is calibrated from O to 500. It is driven from the
main tuning knob to indicate the transceiver's operating
frequency.
@ MAIN TUNING KNOB
This control is used to select the desired operating frequen-
cy. The scale on the control knob is calibrated at 1 kHz in-
tervals, allowing accurate tuning. For exact frequency, read
the Digital Display.
(@). RIT INDICATOR
This light emitting diode indicates the RIT circuit is ON.
@ IF SHIFT CONTROL
By using this control, the IF crystal filter center frequency
can be shifted +1 kHz, allowing adjustment of tone quality,
or eliminating interference from adjacent frequencies.
For normal operation, this control should be set to the center
"0" position (detent).
@ RIT CONTROL
When the RIT circuit is ON, this will vary receive frequency
by about +1.5 kHz. When the control is set to the "0"
center position, there is no frequency shift.
(@ CAR (CARRIER LEVEL) CONTROL
This control is used to adjust the carrier output level only
during CW operation. Adjust the control so the ALC meter
indication is within the ALC zone.
8
(@® MIC (MICROPHONE GAIN) CONTROL
This adjusts mic amplifier gain during SSB operation. Again,
adjust the control so the ALC meter indication is within the
ALC zone.
(@® RF GAIN CONTROL
BAND SWITCH
@) NB (NOISE BLANKER) SWITCH
@ CAL (CALIBRATOR) SWITCH
@ RIT SWITCH
@ VOX GAIN CONTROL
@ DELAY CONTROL
This control is used to adjust the "Hold" time of the VOX cir-
cuit. Clockwise adjustment gives longer hold-time.
@ ANTI-VOX CONTROL
tripped by sound from the speaker.
@ RF ATT SWITCH
Turning this switch ON attenuates antenna input by approx.
20dB to protect the RF amplifier and mixer circuit from too
strong signals.
